That IC only comes out to about an inch, which most of ours are 2+. With that said you may want to look at going to a bigger core or look at your air temps post intercooler. What type of throttle body do you have or what size?
Usually I tune them to run in the 11.0-11.5afr range non intercooled on 91octane. Full size intercooler (2"+), you can get a little leaner as the IC does it's job, around 11.7-12.2. Tuning for higher octane usually reduces the chance for detonation so typically you want a 12.XX afr especially when running at the track. Off the track daily driving, you may want to have a different tune in the high 11's if you run 98 all the time.
For timing, i would at least try to get in the 16-18* range and if not possible, pulley up. At the 4,500+rpm range try to keep the timing rising slowly with rpm's.
